Abstract

Becoming involved in war is an experience that has the potential to shape later-life health. The aim of the present study was to explore Finnish Second World War veterans’ health status and the determinants of self-rated health (SRH) and functional capacity, especially the ability to walk, and to identify risk factors and their combinations that predict late-life mortality among veterans.

The study population comprised Finnish Second World War veterans who participated in the Veteran 1992 and Veteran 2004 Project surveys. In 1992, a postal questionnaire was sent to all 242,720 war veterans living in Finland. The follow-up survey, the Veteran 2004 Project, was conducted with a randomized sample of veterans who participated in the Veteran 1992 Project. The total number of participants in the baseline survey was 177,989 men and 48,745 women, and in the follow-up survey, 4,348 men and 651 women. The response rate was high in both surveys: 93% in 1992 and 87% in 2004. All analyses were conducted separately for men without disability, men with disability and women.

In a cross-sectional study, SRH and functional capacity was found to be better among 80–84-year-old Finnish war veterans in 2004 compared with 1992, although the prevalence of many diseases increased during the follow-up.

Among the 4,999 veterans who participated in both surveys, the majority rated their health as improved or unchanged during the follow-up. Walking difficulties and cardiovascular (CVD), musculoskeletal and neurological diseases were found to be predictors of declined SRH. When exploring functional capacity among veterans, neurological and musculoskeletal diseases, but especially walking difficulties, predicted veterans’ future functional impairment as many as 12 years in advance, and worsening of these conditions was associated with impaired activities of daily living.

During an average 9.9-year follow-up, walking difficulties alone or together with multimorbidity and/or with a third risk factor was the most important risk factor for total and for CVD mortality among all veteran groups.

In conclusion, the majority of veterans rated their SRH as improved or unchanged during the follow-up. The importance of walking difficulties as a determinant of SRH and functional capacity and as a predictor of mortality was confirmed.
